To avoid EMC interference we recommend that the shield on the encoder cables or the
housing of the shielded junction box is only connected to earth at a single point:
A or B or C or D or E
Conductor loops outside the shield must be avoided.
If a shielded junction box is not used, the shield must run continuously from the encoder to
the evaluation device.
